DESCRIPTION OF EMBODIMENTS

Embodiments of the present invention will be described below with reference to the figures.

In the description and the figures, identical elements to those appearing in earlier figures have been allocated identical reference numerals, and where appropriate, detailed description thereof has been omitted.

FIG. 1 is a pattern diagram showing an example of a bed system according to an embodiment.

As shown in FIG. 1 , a bed system 110 according to an embodiment includes an acquisition unit 61I and a first display 61. The acquisition unit 61I acquires a plurality of user interface device information 55 i. The plurality of user interface device information 55 i is acquired from a plurality of user interface devices 55.

The acquisition unit 61I and the first display 61 are included in a first input/output device 60. The first input/output device 60 is a master station device, for example. The first input/output device 60 is capable of communicating with a plurality of bed devices 50.

One bed device 50 among the plurality of bed devices 50 includes one user interface device 55 among the plurality of user interface devices 55. One bed device 50 among the plurality of bed devices 50 includes a bed 51 and the user interface device 55. The user interface device 55 is connected to the bed 51.

The plurality of user interface devices 55 include user interface devices 55A to 55C and so on, for example. The user interface devices 55A to 55C respectively output user interface device information 55 iA to 55 iC and so on. The plurality of user interface device information 55 i (the user interface device information 55 iA to 55 iC and so on) is supplied to the acquisition unit 61I via a server 65 or the like, for example. The number of user interface devices constituting the plurality of user interface devices 55 is a desired integer no smaller than 2. The number of sets of user interface device information constituting the plurality of user interface device information 55 i corresponds to the number of user interface devices constituting the plurality of user interface devices 55.

The acquisition unit 61I is a communication circuit, for example. The acquisition unit 61I includes an electric circuit, for example. The acquisition unit 61I and the plurality of user interface devices 55 exchange information (signals) by a wired or wireless method selected as desired.

The plurality of user interface device information 55 i acquired from the plurality of user interface devices 55 may be supplied to an electronic medical record storage unit 66 or the like via the server 65, for example.

The plurality of user interface devices 55 (the user interface devices 55A to 55C and so on) are provided to correspond respectively to the plurality of beds 51 (beds 51A to 51C and so on).

The bed 51 includes a moving part 70, for example. The moving part 70 includes a back section 70 a, a knee section 70 b, a leg section 70 c, a height modifying part 70 d (a bed elevator, for example), and so on, for example. By operating the moving part 70, at least one of “back-raising”, “knee-raising”, “height adjustment”, and “inclining” can be performed. “Inclining” includes at least one of rolling and tilting.

An actuator or the like, for example, moves the moving part 70. The moving part 70 may include a sensor (a load sensor, for example), for example. Information relating to the state of a user of the bed 51 may be acquired by detecting a load exerted on the actuator. The user is a patient, a care receiver, or the like, for example. For example, the load sensor or the like provided on the moving part 70 may output information relating to the user (at least one of sitting up, sitting on the edge of the bed, bed departure, and “monitoring”, for example). “Monitoring” is a state in which the user remains out of bed continuously for a specified time, for example. When the user remains out of bed continuously for the specified time, the load sensor or the like outputs a signal (information) relating to “monitoring”.

Bed moving part information 51 i is supplied to the user interface device 55 from each of (one of) the plurality of beds 51. The bed moving part information 51 i includes information relating to at least one of the height and the angle of one of the plurality of beds. The bed moving part information 51 i includes whether or not the height of the bed 51 is at a minimum, for example. The bed moving part information 51 i includes information relating to the angle of at least one of the back section 70 a, the knee section 70 b, and the leg section 70 c, for example. The bed moving part information 51 i may also include information relating to the angle of incline of the bed 51.

In this example, the bed 51 is provided with an auxiliary device 52. The auxiliary device 52 is a sheet (or a plate), for example. The auxiliary device 52 is provided between the section of the bed 51 and the mattress, for example. The auxiliary device 52 includes a sensor (at least one of a vibration sensor, a noise sensor, and a force sensor, or the like), for example. The vibration sensor includes an air pressure sensor (a pressure sensor, for example). The auxiliary device 52 is capable of detecting at least one of sleeping, waking up, sitting up, bed departure, monitoring, heart rate, and respiration rate in relation to the user, for example. The detection result is supplied to one of the plurality of user interface devices 55. For example, the sensor included in the auxiliary device 52 detects the user behavior state of the user. The user behavior state includes at least one of bed departure, sleeping, waking up (lying flat in bed), sitting up, and sitting on the edge of the bed in relation to the user of the bed 51. User behavior information 52 i including information relating to the user behavior state is supplied to the plurality of user interface devices 55.

The bed 51 may acquire at least a part of the user behavior information 52 i. When a sensor is provided in the actuator provided on the bed 51, as described above, the bed 51 may detect the user behavior state (a state including at least one of bed departure, sleeping, waking up, sitting up, and sitting on the edge of the bed). The bed 51 may be considered to include the auxiliary device 52.

In this example, measurement information 53 i is also supplied to the user interface device 55. A measurement device 53 acquires the measurement information 53 i. The measurement device 53 includes at least one of a blood pressure gauge 53 a, a pulse oximeter 53 b, a thermometer 53 c, and a blood glucose meter 53 d, for example. The measurement device 53 acquires information (vital signs information, for example) relating to at least one of the blood pressure, the blood oxygen saturation (SpO₂), the blood glucose level, and the body temperature of the user, for example. The blood oxygen saturation is the percutaneous arterial oxygen saturation, for example. The measurement device 53 supplies the vital signs information to the user interface device 55 by communicating with the user interface device 55, for example. This communication is performed by short-range wireless communication, for example. A nurse or the like may input at least a part of the vital signs information into the user interface device 55 manually.

For example, the user interface device 55A (one of the plurality of user interface devices 55) is associated with the bed 51A (one of the plurality of beds 51), an auxiliary device 52A (one of the plurality of auxiliary devices 52), and a measurement device 53A (one of the plurality of measurement devices 53). The user interface device 55B, for example, is associated with the bed 51B, an auxiliary device 52B, and a measurement device 53B. The user interface device 55C, for example, is associated with the bed 51C, an auxiliary device 52C, and a measurement device 53C.

The bed moving part information 51 i, the user behavior information 52 i, and the measurement information 53 i, described above, are supplied to the acquisition unit 61I via the user interface device 55 as the user interface device information 55 i.

In this example, at least a part of the user interface device information 55 i is supplied to a second display 62. The second display 62 is a display of a mobile terminal, for example. A caregiver or the like, for example, uses the second display 62. The caregiver or the like provides the respective users of the plurality of beds with nursing care or medical care. For example, each of a plurality of caregivers or the like owns one second display 62.

At least one of the first display 61 and the second display 62 includes a display device (a liquid crystal display device, an EL display device, or the like, for example), for example. The size (the length of the diagonal of the screen, for example) of the first display 61 is greater than the size (the length of the diagonal of the screen, for example) of the second display 62. The acquisition unit 61I may be provided in a casing in which the first display 61 is provided.

Meanwhile, the plurality of caregivers or the like share the first display 61. The first display 61 is provided in a nurse station or the like, for example. The first display 61 is a display of a master station device, for example. The first display 61 is provided in a different position to the plurality of user interface devices 55. The first display 61 is provided in a location (a remote location) apart from the plurality of user interface devices 55. From the display on the first display 61 provided in a remote location, the caregivers or the like can ascertain the states of the beds 51 connected to the plurality of user interface devices 55 or the states of the users of the beds 51.

The first display 61 displays a plurality of images 61G on a single screen 61D on the basis of the plurality of user interface device information 55 i acquired by the acquisition unit 61I. The plurality of images 61G correspond respectively to the plurality of user interface devices 55.

The single screen 61D displays the plurality of images 61G corresponding respectively to the plurality of user interface devices 55 side by side. The caregivers or the like can thus ascertain the states of the respective users of the plurality of beds 51 efficiently and in an easily understandable manner. As a result, a bed system having improved usability can be provided.

The plurality of beds 51 are provided in a hospital, a care facility, or the like, for example. The user interface devices 55 are provided respectively on the plurality of beds 51. One user interface device 55 can provide the caregiver or the like with information relating to the state of the bed 51 to which the user interface device 55 is connected and the state of the user of the bed 51. Meanwhile, in a nurse station located away from the bed 51, it is necessary to ascertain the states of the plurality of beds 51 and the plurality of users as a whole. By displaying the plurality of images 61G on the single screen 61D, the overall situation can be ascertained. As a result, high-priority measures can be implemented efficiently.

For example, the plurality of user interface device information 55 i acquired from the plurality of user interface devices 55 is displayed at the same time on the single screen 61D of the first display 61. The plurality of images 61G are displayed collectively on the single screen 61D. As a result, the information can be ascertained more easily than in a case where, for example, the plurality of user interface devices 55 are accessed individually from the nurse station and information is acquired from each of the plurality of user interface devices 55.

According to an embodiment, information exchange (communication) is performed rapidly between a plurality of caregivers and the like, for example. Communication delays are suppressed. The productivity of the caregiver or the like improves. Risks to the users can be identified quickly.

As described above, one set of the plurality of user interface device information 55 i includes state information. The state information includes at least one of the bed state information relating to the state of one bed 51 among the plurality of beds 51 and the user state information relating to the state of the user of the one bed 51 among the plurality of beds 51. The bed state information includes, for example, the bed moving part information relating to at least one of the height and the angle of the one bed 51 among the plurality of beds 51. The user state information includes at least one of the vital signs information relating to the user and the user behavior information relating to the user. The vital signs information includes information relating to at least one of the blood pressure, the blood oxygen saturation, the blood glucose level, the heart rate, the pulse rate, the respiration rate, the weight, and the body temperature of the user. The user behavior information includes information relating to at least one of bed departure, sleeping, waking up, sitting up, and sitting on the edge of the bed in relation to the user.

One image among the plurality of images 61G includes a state display (a pictogram, a color, or the like, to be described below) corresponding to the state information described above. As will be described below, when the state information is abnormal, the first display 61 displays a warning display on the one image among the plurality of images 61G.

In an embodiment, as will be described below, the plurality of state information (the bed moving part information 51 i, the user behavior information 52 i, the measurement information 53 i, and so on) included in the user interface device information 55 i is displayed as a single combination. As a result, the state information relating to the states of the plurality of beds 51 and the plurality of users can be displayed clearly on the single screen 61D. By employing a display of combined information, risks can be identified easily and efficiently. For example, signs indicating risk to a user (an injury, a deterioration of the medical condition, and so on) can easily be ascertained from the states of the plurality of beds 51 and the states of the plurality of users at an appropriate timing.

Hence, according to an embodiment, efficiently ascertaining the states of the plurality of beds 51 (states of devices) and the states of the plurality of users in a remote location can be achieved more easily. As a result, an improvement in usability can be achieved. For example, the quality of medical or nursing care can be improved.

A processing device such as a computer, for example, generates data relating to the screen 61D and the plurality of images 61G displayed on the first display 61. The processing device may be provided in the acquisition unit 61I or the first display 61, for example. The processing device may be provided in the server 65 or the like, for example.

Examples of displays displayed on the first display 61 will be described below.

FIG. 2 is a pattern diagram showing an example of a bed system according to an embodiment.

FIG. 2 shows an example of the screen 61D of the first display 61. As shown in FIG. 2 , the single screen 61D displays the plurality of images 61G side by side. In this example, a message is displayed in a message region 61M. For example, the message is a communication state error or the like, for example.

One of the plurality of images 61G includes a first partial region R1, a second partial region R2, and a third partial region R3. In this example, an outer edge partial region R4 is further provided. The outer edge partial region R4 is provided on the periphery of the first partial region R1, the second partial region R2, and the third partial region R3. The plurality of images 61G are displayed within a background region R5 of the single screen 61D. The outer edge partial region R4 clarifies a boundary between the background region R5 and the image 61G.

For example, the background region R5 is white, for example. The outer edge partial region R4 is a pale color (pale blue or the like), for example.

At least a part of the second partial region R2 is positioned between the first partial region R1 and the third partial region R3. For example, the third partial region R3 is positioned around the first partial region R1 and the second partial region R2. The third partial region R3 is frame-shaped, for example.

One of the plurality of images 61G corresponds to one of the plurality of user interface devices 55 (a subject user interface device 55). In other words, one of the plurality of images 61G corresponds to one set of the plurality of user interface device information 55 i. The subject user interface device 55 corresponds to one bed 51 (the subject bed 51) and one user (the subject user). Accordingly, one of the plurality of images 61G corresponds to the subject bed 51 and the subject user. One of the plurality of images 61G will be described below.

The first display 61 displays a pictogram in the first partial region R1, for example. The first display 61 displays the identification information I1 specifying the user in at least a part of the second partial region R2. The first display 61 displays a warning display 30A in the third partial region R3. Examples of these displays will be described below.

A pictogram is displayed in the first partial region R1. The pictogram includes a state display corresponding to the state information (at least one of the bed state information and the user state information). The pictogram includes the bed moving part information 51 i, for example. As described above, the bed moving part information 51 i includes information relating to at least one of the height and the angle of one of the plurality of beds 51. For example, the pictogram includes a pattern (including characters) corresponding to the height of the subject bed 51. For example, the pictogram includes a pattern (including characters) corresponding to the angle of the subject bed 51. The pictogram includes the user state information (for example, the vital signs information and the user behavior information). The pictogram forms at least a part of the state information.

The identification information I1 is displayed in the second partial region R2. In this example, vital signs information I2 is also displayed in the second partial region R2. The identification information I1 specifies the user (the subject user) of one bed (the subject bed 51) among the plurality of beds 51. The identification information I1 includes the name of the subject user, for example. The vital signs information I2 includes information relating to the vital signs of the subject user. The vital signs information I2 includes information relating to at least one of the blood pressure, the blood oxygen saturation, the blood glucose level, the heart rate, the pulse rate, the respiration rate, the weight, and the body temperature of the subject user.

For example, the identification information I1 includes character information (the characters of the name and so on). The vital signs information I2 is displayed according to color. More specifically, in the second partial region R2, the color of the region, excluding the identification information I1, is modified on the basis of the vital signs of the subject user. Thus, the vital signs information I2 may be displayed according to the color on the periphery of the identification information I1. As a result, the condition (the vital signs) of the subject user can be recognized more easily while ensuring that the identification information I1 remains easy to see. An example of display of the vital signs information I2 according to color will be described below.

Hence, the first display 61 displays the identification information I1 and the vital signs information I2 in the second partial region R2. The vital signs information I2 forms at least a part of the state information.

Meanwhile, a warning display 30A is displayed in the third partial region R3. The warning display 30A is displayed when a specific condition is satisfied. When the state information is abnormal, the warning display 30A is displayed in the third partial region R3 of one of the plurality of images 61G. For example, the first display 61 displays the warning display 30A when at least one of the bed-departure state of the subject user, the waking-up state of the subject user, the sitting-up state of the subject user, the sitting-on-the-edge-of-the-bed state of the subject user, the heart rate of the subject user, and the respiration rate of the subject user is abnormal. The first display 61 may also display the warning display 30A in the third partial region R3 when the bed state information is abnormal. As described above, the subject items of the warning display 30A include bed departure, waking up, sitting up, sitting on the edge of the bed, heart rate, respiration rate, and so on. These subject items may be acquired automatically rather than manually, for example. These subject items are acquired continuously without human intervention, for example. Therefore, when an abnormal state occurs among the subject items, it may be difficult to notice the abnormal state. By displaying the warning display 30A in relation to these subject items, more appropriate services can be provided.

A reference (a threshold) for determining whether or not an abnormal state has occurred may be determined in accordance with the state (the condition and so on) of the subject user, for example. For example, when the bed 51 or the auxiliary device 52 of a user who finds walking difficult detects that the user is out of bed, a serious accident such as the user falling from the bed 51 may occur. In this case, a rapid response is necessary. In such cases, the warning display 30A is displayed after detecting the bed departure state. In contrast, when bed departure is detected in relation to a user who finds walking easy, the possibility of a serious accident is comparatively low. In such cases, the warning display 30A need not be displayed even after detecting the bed departure state.

The reference for determining whether or not an abnormal state has occurred may be determined on the basis of a combination of the state of the subject user and the state of the bed 51 or the like, for example. When the bed departure state is detected in relation to a user who finds walking difficult and whose bed 51 is high, the user may fall from the high bed 51. In such cases, the warning display 30A is displayed.

The auxiliary device 52 (or the bed 51) or the like detects information relating to heart rate and respiration rate continuously, for example. As a result, information relating to the steady heart rate and respiration rate of the subject user accumulates. When a dramatic variation from the steady heart rate and respiration rate is observed, the warning display 30A is displayed. When the degree of variation is intermediate, a notification display 30N to be described below may be displayed.

In this example, the notification display 30N is displayed in the third partial region R3. For example, the first display 61 may also display the notification display 30N when at least one of the heart rate of the subject user and the respiration rate of the subject user varies so as to exceed a reference.

For example, the heart rate of the subject user and the respiration rate of the subject user are acquired from the subject bed 51 (one of the plurality of beds) or the auxiliary device 52 of the subject bed 51 (one of the plurality of beds). As described above, the auxiliary device 52 may be considered as a part of the bed 51.

The heart rate of the subject user and the respiration rate of the subject user are detected continuously. When the continuously detected heart rate or respiration rate varies so as to exceed a reference (when an event occurs), the condition of the user may have deteriorated. By displaying the notification display 30N when such evidence of deterioration is found, appropriate countermeasures can be taken rapidly.

The reference used to determine whether or not to display the notification display 30N is determined in accordance with the state of the subject user, for example. A looser reference than the reference used to determine whether or not the display the warning display 30A, for example, is employed as the reference (the threshold) for determining whether or not to display the notification display 30N. For example, a nurse or the like prioritizes care of a user for whom the warning display 30A is displayed over care of a user for whom the notification display 30N is displayed.

By displaying the warning display 30A, the nurse or the like can easily identify the user (the care-receiver) having the highest priority. Further, by displaying the notification display 30N, the nurse or the like can easily identify the user (the care-receiver) having the second highest priority. As a result, the quality of medical or nursing care can be improved, for example.

In this example, a window region 61H is provided on the single screen 61D. At least a part of the information relating to one of the plurality of users, for example, is displayed in the window region 61H. In this example, information relating to the body temperature, the blood pressure (the systolic blood pressure and the diastolic blood pressure), the heart rate, the pulse rate, the respiration rate, the SpO₂, and the blood glucose is displayed. By clicking (touching) one of the plurality of images 61G, for example, the information relating to the subject user corresponding to that image 61G is displayed in the window region 61H.

Hence, when one of the plurality of images 61G receives input, the first display 61 may display the information corresponding to that image 61G. This information forms at least a part of the information relating to the subject user corresponding to the image 61G, for example. The information corresponding to this one image among the plurality of images 61G may be displayed in a part of the single screen 61D, for example (in the window region 61H, for example). By providing the window region 61H on the same screen 61D, the warning display 30A can be presented to a nurse or the like even while the caregiver or the like is viewing the information displayed in the window region 61H, for example. As a result, cases in which the warning display 30A and so on are overlooked can be suppressed.

In an embodiment, the window region 61H may be provided on a separate screen. For example, when one of the plurality of images 61G receives input, the single screen 61D may shift to a different screen. In this case, a different screen can be used, and therefore information relating to the subject user can be displayed in detail.

Several examples of the images 61G will be described below.

FIGS. 3(a) to 3(d) are pattern diagrams showing examples of images displayed in a bed system according to an embodiment.

As shown in FIG. 3(a), the single image 61G is provided with the first partial region R1, the second partial region R2, and the third partial region R3. In this example, an outer edge partial region R4 is further provided. The ward number I3 (in this example, “2221”) of the subject user may be displayed in the outer edge partial region R4.

As described above, the pictogram PG is displayed in the first partial region R1. The identification information I1 and the vital signs information I2 are displayed in the second partial region R2. In this example, the number 14 (in this example, “01”) of the subject user within the ward is displayed in a part of the second partial region R2.

FIG. 3(b) shows an example of the first partial region R1. FIG. 3(c) shows an example of the second partial region R2. FIG. 3(d) shows an example of the third partial region R3.

As shown in FIG. 3(b), the first partial region R1 has a vertical direction length L1 and a lateral direction length W1. As shown in FIG. 3(c), the second partial region R2 has a vertical direction length L2 and a lateral direction length W2. As shown in FIG. 3(d), the third partial region R3 has a vertical direction length L3 and a lateral direction length W3.

In an embodiment, the length L3 is greater than the length L1. The length L3 is greater than the length L2. The length W3 is greater than the length W1. The length W3 is greater than the length W2.

Hence, the vertical direction length L3 and the lateral direction length W3 of the third partial region R3 are long. Accordingly, the outer shape of the third partial region R3 is larger than the outer shape of the first partial region R1 and the outer shape of the second partial region R2. Thus, for example, the warning display 30A or a notification display 30N displayed in the third partial region R3 is clearly visible.

A nurse or the like can identify necessary warnings and notifications in an easily understandable manner.

Meanwhile, for example, the surface area of the second partial region R2 is greater than the surface area of the first partial region R1. For example, the surface area of the vital signs information I2 displayed in the second partial region R2 is greater than the surface area of the pictogram PG displayed in the first partial region R1. The vital signs information I2 often has a higher priority than the information acquired from the pictogram PG. With this surface area relationship, a nurse or the like can identify high-priority information (the vital signs information I2) preferentially.

Examples of displays displayed in the third partial region R3 will be described below.

FIGS. 4(a) to 4(c) are pattern diagrams showing examples of images displayed in a bed system according to an embodiment.

FIG. 4(a) shows a state in which no information is displayed in the third partial region R3. FIG. 4(b) shows a state in which the notification display 30N is displayed in the third partial region R3. FIG. 4(c) shows a state in which the warning display 30A is displayed in the third partial region R3.

As shown in FIG. 4(a), when no information is displayed in the third partial region R3, the state of the third partial region R3 is identical to the state of at least a part of the second partial region R2. For example, the color of the third partial region R3 is the same as the color of the vital signs information I2 in the second partial region R2.

The recognizability of the notification display 30N shown in FIG. 4(b) is higher than the recognizability of the vital signs information I2 in the second partial region R2, for example. The color of the notification display 30N is dark red, for example. The vital signs information I2, on the other hand, is displayed in a pale color (pale pink, pale yellow, pale green, pale blue, or the like, for example). The notification display 30N can thus be recognized more easily.

An attention-alerting property (the recognizability) of the warning display 30A shown in FIG. 4(c) is higher than the attention-alerting property (the recognizability) of the notification display 30N, for example. For example, the warning display 30A may include flashing. The notification display 30N, on the other hand, does not flash. The warning display 30A includes a distinctively shaped pattern 30Aa, for example. The distinctively shaped pattern 30Aa is not provided in the notification display 30N. In this example, the distinctively shaped pattern 30Aa is displayed in the shape of a “bell”. Due to the distinctively shaped pattern 30Aa, the surface area of the warning display 30A is larger than the surface area of the notification display 30N. Thus, the warning display 30A has at least one of a larger surface area than the notification display 30N and a different pattern to the pattern included in the notification display 30N, for example. As a result, the attention-alerting property of the warning display 30A is higher than the attention-alerting property of the notification display 30N.

The color of the warning display 30A may be different to the color of the notification display 30N. For example, the warning display 30A is dark red. The notification display 30N may have a red color that is paler than the color of the warning display 30A. For example, the chroma of the warning display 30A may be higher than the chroma of the notification display 30N.

As shown in FIG. 4(c), the region displaying the distinctively shaped pattern 30Aa forming a part of the warning display 30A is considered part of the third partial region R3. As shown in FIGS. 4(a) and 4(b), when the warning display 30A is not displayed, this part of the third partial region R3 is identical to the state of at least a part of the second partial region R2. For example, the color of this part of the third partial region R3 is the same as the color of the vital signs information I2 in the second partial region R2.

Examples of displays displayed in the second partial region R2 will be described below.

FIGS. 5(a) to 5(c) are pattern diagrams showing examples of images displayed in a bed system according to an embodiment.

These figures correspond to the plurality of information displayed in the second partial region R2. As described above, the identification information I1 (character information such as a name, for example) and the vital signs information I2 (color information, for example) are displayed in the second partial region R2. For example, at least a part of the vital signs information I2 is between the identification information I1 and the third partial region R3 (the warning display 30A and the notification display 30N).

In this example, the vital signs information I2 is displayed according to color. In this example, the vital signs information I2 is displayed using three colors (a first color C1, a second color C2, and a third color C3). FIGS. 5(a) to 5(c) correspond respectively to the three colors.

The first color C1, shown in FIG. 5(a), corresponds to “normal”, for example. The second color C2, shown in FIG. 5(b), corresponds to “caution”. The third color C3, shown in FIG. 5(c), corresponds to “warning”.

For example, the chroma of the third color C3 is higher than the chroma of the second color C2. The chroma of the second color C2 is higher than the chroma of the first color C1. The third color C3 is darker than the second color C2. The second color C2 is darker than the first color C1. As a result, for example, the third color C3 is more easily recognizable than the other two colors. As a result, the second color C2 is more easily recognizable than the first color C1.

For example, the third color C3 is a color close to red. The first color C1 is a color distant from red. For example, an absolute value of a difference between a hue of the third color C3 and a hue of red is smaller than an absolute value of a difference between a hue of the second color C2 and the hue of red. For example, the absolute value of the difference between the hue of the second color C2 and the hue of red is smaller than an absolute value of a difference between a hue of the first color C1 and the hue of red.

For example, the third color C3 is pale red. The second color C2 is pale yellow. The first color C1 is substantially white.

When the warning display 30A (or the notification display 30N) displayed in the third partial region R3 is a red-based color, the color of the warning display 30A (or the notification display 30N) is darker than the color (pale red, for example) of the third color C3.

For example, the chroma of the notification display 30N is higher than the chroma of the display of the vital signs information I2. The chroma of the notification display 30N is higher than the chroma of the first color C1, higher than the chroma of the second color C2, and higher than the chroma of the third color C3. As a result, the attention-drawing ability of the notification display 30N can be enhanced.

For example, an absolute value of a difference between a hue of the notification display 30N and the hue of red is smaller than an absolute value of a difference between a hue of the display of the vital signs information I2 and the hue of red. For example, the absolute value of the difference between the hue of the notification display 30N and the hue of red is smaller than the absolute value of the difference between the hue of the first color C1 and the hue of red. The absolute value of the difference between the hue of the notification display 30N and the hue of red is smaller than the absolute value of the difference between the hue of the second color C2 and the hue of red. The absolute value of the difference between the hue of the notification display 30N and the hue of red is smaller than the absolute value of the difference between the hue of the third color C3 and the hue of red. As a result, the attention-drawing ability of the notification display 30N can be enhanced.

For example, the chroma of the warning display 30A is higher than the chroma of the display of the vital signs information I2. For example, the chroma of the warning display 30A is higher than the chroma of the first color C1, higher than the chroma of the second color C2, and higher than the chroma of the third color C3. As a result, the attention-drawing ability of the warning display 30A can be enhanced.

For example, an absolute value of a difference between a hue of the warning display 30A and the hue of red is smaller than the absolute value of the difference between the hue of the display of the vital signs information I2 and the hue of red. For example, the absolute value of the difference between the hue of the warning display 30A and the hue of red is smaller than the absolute value of the difference between the hue of the first color C1 and the hue of red. The absolute value of the difference between the hue of the warning display 30A and the hue of red is smaller than the absolute value of the difference between the hue of the second color C2 and the hue of red. The absolute value of the difference between the hue of the warning display 30A and the hue of red is smaller than the absolute value of the difference between the hue of the third color C3 and the hue of red. As a result, the attention-drawing ability of the warning display 30A can be enhanced.

For example, the vital signs information I2 has a pale color. The vital signs information I2 is displayed close to the identification information I1. When the vital signs information I2 has a dark color, the recognizability of the identification information I1 deteriorates. By displaying the vital signs information I2 in a pale color, a nurse or the like can identify the desired vital signs information I2 in an easily understandable manner while the identification information I1 remain highly recognizable.

For example, when the warning display 30A or the notification display 30N is displayed, the identification information I1 is preferably clearly visible. Thus, the caregiver or the like can identify the user in relation to whom a warning or a notification has been issued in an easily understandable manner. The identification information I1 is preferably black (a dark color), for example. Thus, high recognizability is acquired in relation to the identification information I1.

The display of the vital signs information I2, meanwhile, is displayed according to color. As a result, the caregiver or the like can recognize the medical condition of the subject user intuitively, in an easily understandable manner. The color is comparatively pale. Thus, deterioration of the recognizability of the identification information I1 can be suppressed.

The warning display 30A (or the notification display 30N) needs to have a superior attention-drawing ability. By making the color of the display of the vital signs information I2 comparatively pale, the attention-drawing ability of the warning display 30A (or the notification display 30N) can be enhanced.

As described above, at least a part of the pale-colored vital signs information I2 is between the identification information I1 and the third partial region R3 (the warning display 30A and the notification display 30N). Thus, a situation in which the identification information I1 becomes difficult to see when the warning display 30A or the notification display 30N is displayed can be suppressed.

As described above, the third partial region R3 in which the warning display 30A or the notification display 30N is displayed has a larger outer shape than the first partial region R1 and the second partial region R2. As a result, a superior attention-drawing ability is acquired in relation to the warning display 30A or the notification display 30N. By making the color of the vital signs information I2 pale, the identification information I1 remains clearly visible even when the warning display 30A or the notification display 30N is displayed.

By combining the second partial region R2 and the third partial region R3 in this manner, the warning display 30A or the notification display 30N can be recognized in an easily understandable manner. Further, since the vital signs information I2 is displayed in the second partial region R2 according to color, the caregiver or the like can recognize the medical condition of the subject user intuitively, in an easily understandable manner.

In an embodiment, as described above, the pictogram PG is displayed in the first partial region R1. Hence, from the single image 61G, the caregiver or the like can easily recognize the overall situation, including the state of the subject bed 51 (the bed moving part information 51 i) and the state of the subject user (the user behavior information 52 i) in an easily understandable manner.

The real-time property of the warning display 30A or the notification display 30N is superior to that of the vital signs information I2. A bold color is used for the warning display 30A or the notification display 30N having a superior real-time property. As a result, the warning display 30A or the notification display 30N can be recognized rapidly.

Several examples of the pictogram PG displayed in the first partial region R1 will be described below.

FIGS. 6(a) and 6(b) are pattern diagrams showing examples of images displayed in a bed system according to an embodiment.

These figures show examples of the pictogram PG. In these examples, the information (the bed moving part information 51 i) relating to the subject bed 51 is displayed by a bed moving part display 51 iD.

As shown in FIG. 6(a), in this example, the height of the subject bed 51 is displayed using a height display pattern 11. In this example, the height display pattern 11 has a downward-pointing triangular shape. When the height display pattern 11 is displayed, the height of the bed is low (at the lowest level, for example).

As shown in FIG. 6(b), the height display pattern 11 is not displayed, for example. This state indicates that the height of the bed is high (above floor level, for example), for example.

Thus, the presence or absence of a display pattern (the height display pattern 11 or the like) can be used as the bed moving part display 51 iD.

FIGS. 7(a) to 7(j) are pattern diagrams showing examples of images displayed in a bed system according to an embodiment.

These figures show examples of the pictogram PG. In these examples, an angle display pattern 12 and angle display characters 13 are used as the bed moving part display 51 iD of the pictogram PG.

In the examples shown in FIGS. 7(a), 7(c), 7(e), 7(g), and 7(i), the angle display pattern 12 extends in a lateral direction (a horizontal direction). This angle display pattern 12 indicates that the angle of the bed 51 (the angle of the back section 70 a, for example) is small (a horizontal state in which the angle is 0 degrees, for example). FIGS. 7(a), 7(e), and 7(i) are used when the subject user is out of the bed 51 (i.e. in a bed departure state), for example. FIGS. 7(c) and 7(g) are used when the subject user is lying flat on the bed 51, for example.

In the examples shown in FIGS. 7(b), 7(d), 7(f), 7(h), and 7(j), the angle display pattern 12 is inclined. This angle display pattern 12 indicates that the angle of the bed 51 is large (30 degrees or the like, for example). In these examples, the angle display characters 13 indicating the approximate angle of incline are also displayed. FIGS. 7(b), 7(f), and 7(j) are used when the subject user is out of the bed 51 (i.e. in a bed departure state), for example. FIGS. 7(d) and 7(h) are used when the subject user is lying flat on the bed 51, for example. It is acceptable to display at least one of the angle display pattern 12 and the angle display characters 13.

The color of the angle display pattern 12 in FIGS. 7(a) to 7(d) is different to the color of the angle display pattern 12 in FIGS. 7(e) to 7(h). The color of the angle display pattern 12 in FIGS. 7(a) to 7(d) is different to the color of the angle display pattern 12 in FIGS. 7(i) and 7(j). The color of the angle display pattern 12 in FIGS. 7(e) to 7(h) is different to the color of the angle display pattern 12 in FIGS. 7(i) and 7(j). As will be described below, these colors may be determined in accordance with the state of the subject user, such as waking up, sleeping, and bed departure, for example.

FIGS. 8(a) to 8(l) are pattern diagrams showing examples of images displayed in a bed system according to an embodiment.

These figures show examples of the pictogram PG. In these examples, the height display pattern 11, the angle display pattern 12, the angle display characters 13, and a user behavior display 14 are displayed as the pictogram PG. The user behavior display 14 corresponds to the user behavior information 52 i. As described above, the user behavior information 52 i includes information relating to the user behavior state, including at least one of bed departure, sleeping, waking up, sitting up, and sitting on the edge of the bed, in relation to the user of the bed 51. In this example, the user behavior state is classified as one of three states, namely sleeping, waking up, and bed departure. Three display patterns are used as the user behavior display 14.

In the examples shown in FIGS. 8(a), 8(d), 8(g), and 8(j), the user behavior display 14 corresponding to sleeping is displayed. In the examples shown in FIGS. 8(b), 8(e), 8(h), and 8(k), the user behavior display 14 corresponding to waking up is displayed. In the examples shown in FIGS. 8(c), 8(f), 8(i), and 8(l), the user behavior display 14 corresponding to bed departure is displayed.

As illustrated by these figures, the single pictogram PG includes a set of the height display pattern 11, the angle display pattern 12, the angle display characters 13, and the user behavior display 14.

The color (a fourth color C4) of the user behavior display 14 corresponding to sleeping may differ from the color (a fifth color C5) of the user behavior display 14 corresponding to waking up. The fourth color may differ from the color (a sixth color C6) of the user behavior display 14 corresponding to bed departure. The fifth color C5 may differ from the sixth color C6.

For example, when the user is awake on the bed 51, the possibility of an accident or the like may be higher than when the user is asleep on the bed 51. Therefore, the attention-drawing ability of the color (the fifth color C5) used when the user is awake on the bed 51 is preferably higher than the attention-drawing ability of the color (the fourth color C4) used when the user is asleep on the bed 51.

For example, the chroma of the fifth color C5 is higher than the chroma of the fourth color C4. For example, the absolute value of the difference between the hue of the fifth color C5 and the hue of red is smaller than the absolute value of the difference between the hue of the fourth color C4 and the hue of red. For example, the fourth color C4 is pale blue and the fifth color C5 is pale yellow.

When the user is out of bed, meanwhile, it is impossible to ascertain another state of the user from the information acquired from the bed 51 (or the auxiliary device 52). Hence, the color (the sixth color C6) used when the user is out of bed may be an unobtrusive color. For example, the chroma of the sixth color C6 is lower than the chroma of the fourth color C4. For example, the sixth color C6 is gray.

FIGS. 9(a) to 9(d) are pattern diagrams showing examples of images displayed in a bed system according to an embodiment.

These figures correspond to cases in which the pictogram PG displays the bed moving part display 51 iD (information relating to the subject bed 51) but does not display the user behavior display 14 (sleeping, waking up, bed departure, and so on, for example). The height display pattern 11, the angle display pattern 12, and the angle display characters 13 are displayed as the bed moving part display 51 iD of the pictogram PG.

FIGS. 10(a) to 10(c) are pattern diagrams showing examples of images displayed in a bed system according to an embodiment.

These figures correspond to cases in which the pictogram PG does not display the bed moving part display 51 iD but does display the user behavior display 14 (sleeping, waking up, bed departure, and so on, for example).

Thus, various modifications can be applied to the pictogram PG.

For example, in an embodiment, information such as the state of the bed 51, the behavior state of the user of the bed 51, and the medical condition of the user, for example, is presented in a location (a remote location) away from the bed 51. The state of the bed 51 includes an operation state, a setting state, an error state, and so on of the bed 51. The state of the bed 51 may also include the state of the user interface device (an operation state, a setting state, an error state, and so on). The behavior state of the user includes at least one of bed departure, sleeping, waking up (lying flat on the bed), sitting up, and sitting on the edge of the bed, for example. The medical condition of the user includes normal, poor, critical, and so on, for example. The medical condition of the user includes at least one of heart rate, respiration rate, blood pressure, blood oxygen saturation, blood glucose level, and body temperature, for example. On the basis of the state of the bed 51, the behavior state of the user of the bed 51, the medical condition of the user, and so on, a doctor, a nurse, or the like, for example, implements treatment, issues instructions, confirms risk, and so on. By presenting the state of the bed 51, the behavior state of the user, the medical condition of the user, and so on in relation to the plurality of beds 51 on a single screen in a remote location, a nurse or the like can recognize the information quickly and efficiently.

In an embodiment, information having a superior real-time property (the warning display 30A or the notification display 30N) is displayed in a large size (vertical direction length and lateral direction length) and in a bold color, for example. Meanwhile, high-priority information (the vital signs information I2 and so on, for example) is displayed over a large surface area in a pale color or the like. Further, information relating to the state of the bed 51 and the state of the user (the bed moving part information 51 i and the user behavior information 52 i, for example) is combined and displayed using the pictogram PG.

Hence, when a plurality of information is displayed on the single screen 61D in relation to the plurality of beds 51, an improvement in the recognizability (including the attention-drawing ability) of the plurality of information can be expected.

The user interface device 55 is provided for each of the plurality of beds 51. As a result, information relating to the plurality of beds 51 and the plurality of users can be collected from each bed 51. The information acquired by the plurality of user interface devices 55 is supplied to the acquisition unit 61I via a server, for example.

According to an embodiment, a nurse or the like, for example, can collect information more quickly. Risks can be ascertained early, leading to an improvement in the quality of medical care or nursing care.

The bed system 110 according to an embodiment may further include the plurality of beds 51. The plurality of user interface devices 55 are connected respectively to the plurality of beds 51. The bed system 110 may further include the auxiliary device 52. The bed system 110 may further include a second display 62. The bed system 110 may further include the server 65. The bed system 110 may further include an electronic medical record storage unit 66.

As described above, one (each) of the plurality of bed devices 50 includes the bed 51 and the user interface device 55. The user interface device 55 is connected to the bed 51. The user interface device 55 may be provided as a separate component to the bed 51, for example. For example, the user interface device 55 may be provided separately to the bed 51 (or components (a side rail, a frame, and so on) included in the bed 51). By providing the user interface device 55 as a separate component to the bed 51, the combination of the bed 51 and the user interface device 55 can be modified, for example. As a result, various situations can be dealt with easily, leading to a further improvement in usability.

An example of the first input/output device 60 will now be described.

FIG. 11 is a pattern diagram showing an example of a part of a bed system according to an embodiment.

FIG. 11 is a block diagram of the first input/output device 60. As shown in FIG. 11 , the first input/output device 60 includes, for example, a communicator 60 a, a user interface device 60 b (an input reception unit), a display 60 c (the first display 61, for example), a short-range communicator 60 d, an output device 60 e, a storage unit 60 f, and a controller 60 g (a processing unit).

The communicator 60 a includes a communication interface circuit, for example. The communicator 60 a communicates with another device (the plurality of bed devices 50, for example) using a wired or wireless method selected as desired. For example, communication may be performed via the server 65.

The user interface device 60 b includes a keyboard, a pointing device (a mouse, a tablet, or the like), and buttons or a touch panel, for example. The user interface device 60 b receives input.

The display 60 c includes a display device. The display 60 c displays information, for example. The display 60 c may display at least one of the notification display 30N and the warning display 30A, for example. The display 60 c, the user interface device 60 b, and the display 60 c may be integrated.

The short-range communicator 60 d communicates with various devices, for example. For example, communication is performed between an identification tag or the like carried by the caregiver or the like and the short-range communicator 60 d. As a result, the caregiver or the like is identified and so on. Communication by the short-range communicator 60 d is based on a wireless system, for example.

The output device 60 e includes at least one of a speaker 60 ea (a speaker or the like, for example) and a lighting device 60 eb (a light-emitting element or the like, for example), for example. The output device 60 e issues reports, for example.

The storage unit 60 f includes a magnetic hard disk device, a semiconductor storage device, or the like, for example. The storage unit 60 f stores the plurality of user interface device information 55 i, for example. The storage unit 60 f stores a program of the processing executed by the controller 60 g and so on, for example.

The controller 60 g includes an electronic circuit (a CPU: Central Processing Unit or the like, for example), for example. The controller 60 g executes processing based on the program, for example. For example, the controller 60 g compares the measurement values with the set values and so on, for example. The controller 60 g then causes at least one of the display 60 c and the output device 60 e to issue a report in accordance with the comparison result.

FIG. 12 is a flowchart showing an example of an operation performed in a bed system according to an embodiment.

FIG. 12 shows an operation performed by a controller (the controller 60 g, for example) according to an embodiment. For example, the controller 60 g acquires the user interface device information 55 i (step S110). The user interface device information 55 i includes the measurement values of the plurality of items in the plurality of bed devices 50. The controller 60 g determines whether or not the measurement values exceed set ranges (a range determined by the first set value, a range determined by the first set value, and so on). When a measurement value exceeds a set range, the controller 60 g causes another device (the display 60 c, the output device 60 e, or the like) to issue a report (step S130). The processing then returns to step S110. When the measurement values do not exceed the set ranges, on the other hand, the processing returns to step S110. By implementing this processing, reports are issued appropriately.

Examples of the user interface device 55, the second display 62, and the server 65 will be described below. FIG. 13 is a pattern diagram showing an example of a part of a bed system according to an embodiment.

FIG. 13 is a block diagram of the user interface device 55. As shown in FIG. 13 , the user interface device 55 includes, for example, a communicator 50 a, a user interface device 50 b (an input reception unit), a display 50 c, a short-range communicator 50 d, an output device 50 e, a storage unit 50 f, and a controller 50 g (a processing unit). The output device 50 e includes at least one of a speaker 50 ea (a speaker or the like, for example) and a lighting device 50 eb (a light-emitting element or the like, for example), for example.

FIG. 14 is a pattern diagram showing an example of a part of a bed system according to an embodiment.

FIG. 14 is a block diagram of a terminal device including the second display 62. As shown in FIG. 14 , the terminal device includes, for example, a communicator 62 a, a user interface device 62 b (an input reception unit), a display 62 c, a short-range communicator 62 d, an output device 62 e, a storage unit 62 f, and a controller 62 g (a processing unit). The output device 62 e includes at least one of a speaker 62 ea (a speaker or the like, for example) and a lighting device 62 eb (a light-emitting element or the like, for example), for example.

The configuration described in relation to the communicator 60 a can be applied to the communicator 50 a and the communicator 62 a. The configuration described in relation to the user interface device 60 b can be applied to the user interface device 50 b and the user interface device 62 b. The configuration described in relation to the display 60 c can be applied to the display 50 c and the display 62 c. The configuration described in relation to the short-range communicator 60 d can be applied to the short-range communicator 50 d and the short-range communicator 62 d. The configuration described in relation to the output device 60 e can be applied to the output device 50 e and the output device 62 e. The configuration described in relation to the storage unit 60 f can be applied to the storage unit 50 f and the storage unit 62 f. The configuration described in relation to the controller 60 g can be applied to the controller 50 g and the controller 62 g. The controller 50 g and the controller 62 g may implement the operation (see FIG. 12 ) described in relation to the controller 60 g.

The terminal device including the second display 62 may issue the report, for example. At least one of the plurality of user interface devices 55 may issue the report, for example. When one of the plurality of user interface devices 55 issues the report, a report relating to that user interface device 55 is issued.
